Title: Scroll type compressor
Inventor: KIMATA HISAYUKI
IPC: F04C18/02
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To stably maintain sealability of a high-pressure room and to improve assembling property of a scroll type compressor. SOLUTION: Since a seal margin between a fixed scroll 9 and a cover 15 is increased by engagement of a bolt insertion engaging seat 150 of a cover 15 with a bolt insertion part 91, the sealability of the high-pressure room HR can be provided more stably. When the cover 15 is formed by casting, the cover 15 can be increased in rigidity and withstand action of high-pressure gas such as pushing up, and the cover 15 is not floated up. The sealing performance of the high-pressure room can be thereby stably maintained.

Title: Program execution control system and method therefor
Inventor: YAMAZAKI MASAYUKI
IPC: G06F9/38
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To make it possible to control the conditional execution of many succeeding instructions by an execution control instruction having short word length in order to suppress a branch hazard in an information processor for executing the pipeline processing of an instruction. SOLUTION: An execution control instruction having a condition field 42 for specifying an execution condition and an instruction specification field 43 for specifying the number of instructions to be executed at their execution by a binary code is adopted. At the time of receiving the execution control instruction, an invalidation controller 30 judges whether a specific execution condition EC specified by the field 42 comes into effect or not on the basis of a control flag CF from an operation part and determines whether N (N is a natural number) instructions specified by the field 43 out of the succeeding instructions of the execution control instruction are to be invalidated or not in accordance with the judged result.  At the time of determining that N succeeding instructions are to be invalidated because the condition EC fails, the controller 30 asserts a null signal NUL to the operation part.

Title: Network unit and authentication server
Inventor: SANETO TORU
IPC: H04L9/32
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a network unit that can connect a device of a 3rd party other than members of a LAN to the LAN with security. SOLUTION: An address conversion function block 10a converts a destination address (IP address) in a communication packet sent by a terminal 14 into an IP address of a terminal and a server in an existing LAN. According to the operation above, a terminal 14 can utilize the existing LAN 12 even when a user of the terminal 14 does not know the address of a server or the like in the existing LAN. As a result, having only to connect the terminal 14 to the existing LAN allows the terminal 14 to easily utilize the facility of the existing LAN 12. Since the terminal 14 accesses the existing LAN 12 via the network unit 10, the terminal 14 cannot obtain a concrete IP address in the existing LAN 12. Thus, leakage of the IP address can be prevented and the security can be maintained.

Inventor: MITSUMOTO TETSUJI
IPC: F28F27/02
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger for gas containing easy-to-polymerize substance provided with a gas diffuser between a heat exchanging gas introduction opening and a heat exchanging section. SOLUTION: The heat exchanger comprises a shell having a heat exchanging gas introduction opening and a heat exchanging gas delivery opening, and a heat exchanging section for circulating fluid introduced from the outside of the shell between the gas introduction opening and the gas delivery opening, wherein a gas diffuser is provided between the gas introduction opening and the heat exchanging section. Transverse sectional area of the gas diffuser is set equal to 1.0-10.0 times of the cross sectional area of the gas introduction opening. When gas containing easy-to-polymerize substance touches a structure, the gas condenses on the contact face to produce a polymer. The inventive heat exchanger dissipates heat uniformly by diffusing the gas uniformly to the heat exchanging section, thus retarding condensation of gas and preventing polarization of the easy-to-polymerize substance.
